To all whom it may concern,.-

Be it known that I, WILLIAM W. DINGEn, a citizen of the United States,residing at Racine, in the county of Racine and State of 5 IVisconsin,have invented certain new and useful Improvements in Band- Cutters andFeeders 5 and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others Ioskilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described,reference being had to the accompanying drawings, which illustrate oneform in which Ihave contemplated embodying it, and said invention isfully disclosed in the following description and claims.

Referring to the said drawings, Figure l represents a side elevation ofmy improved 2o band-cutter and feeder. Fig. 2 represents a longitudinalsectional view of the same. Fig. 3 represents a rear elevation of thedevice, showing the feeding-conveyor in section. Fig. 4. is a detail endview of the crank which drives the cutting-bars. Fig. 5 represents anelevation of the central portion of the device from the side oppositethat shown in Fig. l. Figs. 6, 7, and 8 are detail views of theautomatic governor for the feedingconveyer.

3o Fig. 9 represents a section through the outer end of the saidconveyer.

In the drawings, A represents the cylindercasing of a thrashing-machineto which my improved band-cutter and feeder is attached,

3 5 and B represents the cylinder thereof.

C represents the hood or casing of the bandcutter mechanism proper,which is preferably permanently attached to the machine, although it maybe removed when desired and 4o may be adapted to be attached to anyordinary thrashing-machine.

D is a removable bottom board, which has one end supported adjacent to,and in this instance by, the concave B and has its other edge providedwith a supporting-rod d, the projecting ends of which are engaged byspring-hangers CZ, secured to the exterior of the casing C and providedwith notches for engaging said rod.

E represents the movable hopper-bottom which forms the bottom of thecasing C. I

, spaces between ad prefer to form this bottom of a series of slats e,preferably of wood, between which are a series of vertically-disposedsaws or notched blades e'. The saws e are each provided 55 along theirlower edge with a horizontal fiange e2, (see Fig. 3,) which extendslaterally .away from the slat c, to which the saw is attached, andengages a recessed portion on the under side of the next adjacent slat.It will thus 6o be seen that these flanges c2 will cover the jacentslats, thus allowing said slats to shrink or swell without leavingopenings through which grain would otherwise fall. The slats earesecured together by transversely-extendin g cleats e3, (see Fig. 2,) towhich are secured pitmen f, engaging cranks f on a shaft F, extendingtransversely of the casing C and operated, as hereinafter described, forthe purpose of impartinga cir- 7o cular movement to the rear end of thehopperbottom. The rear ends of the slats e, forming thehopper-bottom,have a sliding engagement with and are supported by theremovable bottom board D. As the shaft Fforms the support for the frontend of the hopper-bottom E, it is obvious that by removing the bottomboard D, by springing the hangers CZ out of engagement with the rod d,the hopper-bottom may be lowered into the position shown in 8o dottedlines in Fig. 2. This will Aenable an operator to stand under the casingC and have access to the cylinder B to insert new teeth or for any otherpurpose.

In the upper part of the casing C the crankshaft G is mounted insuitable bearings. This shaft is provided with a series of cranks,preferably six in number, arranged at equal distances about a commoncenter of rotation, as shown in Fig. 3 and in the end view, Fig. 9o 4.To each of the cranks g is secured one end of a cutter-bar forming apart of the band-cutting mechanism. Each of these bars consists in thisinstance of a wooden bar I-I, having a bearing portion engaging' a crankg 95 and provided at its rear end with a downwardly-inclined rod or barh, which engages a supporting-rod I, extending transversely of thecasing C and supported by the side walls thereof. To the wooden bar IIis secured a roo metal bar h', having its ends secured to the bar II andbraced centrally by a combined spacing-block and guide h2, which engagesthe bar h' intermediate its ends to prevent the vibration or bending ofthe same. To the bar h are secured a series of knives, preferably formedlike the sections of a mower cutter-bar and riveted or otherwise securedto the bar, so as to be readily replaced when broken. It will be seenthat each of the cutter-bars will have a circular movement at one endand a sliding movement at the other end and that by reason of the numberof cutting knives or sections and the placing of the cranks in themanner described the machine will operate very thoroughly and surely incutting J[he bands and spreadin g the sheaves. The casing C is providedwith a door C' on its upper side to give access to the cuttingbars whendesired.

K represents the frame of the feeding conveyer or carrier, which isconstructed .in the Iusual manner and is provided with the endless apronK', which engages suitable rollers on a shaft 7c at the rear end of theframe, mounted in rigid bearings, and a shaft 7o' at the forward end,which is adjustable toward and from the shaft 7a. The sides of thecarrier-frame are provided with slots 7a2 at its forward end, throughwhich the shaft k' passes, and said shaft is provided at each end with apinion 7e3, (see Figs. 1 and 9,) which engages with a rack 7a4, formedon a casting secured to the frame of the carrier. Upon one end of theshaft 7u' is a grooved pulley h5, rigidly keyed to the shaft andprovided with an eye or other suitable means whereby one end of a rope,chain, or other flexible connection 7e may be secured rigidly in thegroove of said pulley. The rope is then given one or more winds aboutthe pulley and its free end is provided with a loop by which it may besecured to some stationary object. In this instance l have shown one ofthe supportinglegs L for the carrier provided with a pin Z, which can beplaced in one of several adjusting-apertures Z', and the end of the rope7551s conveniently attached to this pin. It will thus be seen that bydrawing` on the rope k the grooved pulley 705 can be revolved in adirection to cause the pinions 7c3 to move forward with respect to theracks 7e', thus carrying the shaft 7e' forward and tightening the apronK', and the desired degree of tension on the apron can be obtained bymeans of the pin Z and the apertures Z' just described. lf for anyreason it should be desired to stop the movement of the carrier-apron,it is simply necessary to disengage the. rope 7s from the pin l, whenthe weight of the carrier-apron will cause the shaft 7e' to moverearwardly, thus slacking the apron, so that it will not be operated bythe driving-shaft 7e'. It will be understood that the apron-supportin grollers on the shaft 7twill turn with the shaft and those upon the shaft7c' loosely thereon.'

The carrier K is adapted to be removably secured in relation to thecasing C, and to this end the said casing is provided near its loweredge with a metal plate or casting C2, which is provided with an openslot or recess c, having a laterally-extending flange c' surroundingthe` same, there being one of these plates on each side of the machine.The slots c c are of a size adapted to receive collars L7 k7, formingthe bearings for the apron-driving shaft 7e, and after said collars areplaced in engagement with said recesses pins c2 c2 are passed downwardthrough apertures in the iianges c' in front of said collars, therebyretaining the rear end of the carrier in engagement with the casing C,as clearly shown in 1 and 3. The carrierK is supported intermediate itsends'by the legs L,which are preferably pivotally secured to thecarrier, the said legs being provided with a series of holes Z2 foradjusting the height at which the carrier is to be supported whendesired.

The crank-shaft G is provided in this instance on the right side of themachine (shown in Fig. l) with a large band-cutter G', which receivespower from a small pulley Z1 on the cylinder-shaft. On the shaft G is asprocketwheel G2, engaged by a sprocket-chain G3, which also passes overa sprocket-wheel M on a stud m, secured to the plate C2. A pinion m' isformed integrally with the sprocket M and engages a similar pinion f2 onthe shaft F, thereby imparting motion to the movable hopper-bottom E. Onthe opposite side of the machine the crank-shaft G is provided with aband-wheel G4, which is engaged by a belt passing over a governor N,mounted on a stud secured to the plate 0 2 and having a pinion nconnected therewith, which pinion meshes with a gear K2 on thedriving-shaft 7s of the carrier-apron. It will thus be seen that thegovernor directly controls the carrier-apron and no other part of themachine, and by this means the chokingof the machine will be prevented,as hereinafter described.

The governor N includes among its members the following elements: N'represents a sleeve for engaging the stud which supports the governor,the said sleeve being provided with a disk N, provided with a peripheralflange. N2 represents a similar disk provided with a peripheralflangen', the inner face of which is turned accurately, so as to form afriction-surface. The disk N2 is provided with the pinion n, preferablyformed integrally therewith and forming the hub of the disk, which turnsupon a reduced portion of the sleeve N'. To the disk N of the governorare pivotally secured a pair of weighted arms nmlich are providedadjacent to their points of pivoting with removable friction-blocks n3,which are driven into dovetailed recesses in said weighted arms, andsaid friction-blocks are further provided with a friction-surface ofleather, rubber, or other suitable material, which is secured to theremovable frictionblock in any desired way. I prefer to form theseblocks ofwood, as they can be renewed when necessary and thefriction-coverin g can be tacked, glued, nailed, or otherwise securedIOC) IIO

to the wooden block more conveniently than it could be attached to metalparts.

The weighted arms n2 are held in their inmost position by means of acoiled spring a5, which surrounds a guide-rod n, pivotally engaging saidweighted arms and connecting the same for joint movement. The spring71,5 engages one of said arms at one end and at the other end an eye n?,through which the guide-rod n passes, the said eye forming a part of anadjusting-rod ns, the end of which passes through a perforated lug 17,9,formed integrally with the disk N, and is provided with an adjusting-nutn10. The disk N is provided with a recess or aperture n adjacent to theadjusting-nut n10, so as to allow it to be turned from the outer side ofsaid disk. Byreference to Figs. G, 7, and S the construction oi' thisgovernor will be apparent and it will be seen that when the disk N isrotated at a slow speed by means of a belt from the pulley G4, as shownin Figs. 3 and 5, the weighted arms will remain in their inner positionsand the friction-surfaces will not engage the friction-flange n of thedisk N2, so that the pinion n will not be rotated and no motion will beimparted to the carrier-apron. lVhen, however, the governor-disk N isrotated at a sufficient speed to throw the weighted arms n2 outwardly,so as to bring the friction-surfaces n4 into operative relation with thefriction-flange n', the pinion fn and disk N2 will be rotated, thusimparting motion to the carrier-apron. The spring n of the governor willbe so adjusted that the Weighted arms will not be thrown out, so as tocouple the disks N and N2 together, until sufficient speed has beenattained by the parts of the thrasher and the shaft G to thoroughlythrash the grain, when the parts will be automatically coupled togetherand the carrier-apron will be thrown into operation. Should the speed ofthe cylinder decrease for any cause,

so as not to be able to thoroughly thrash the grain, this will cause aslowing up of the bandcutting and feeding mechanism and will instantlyeffect the stoppage of the carrierapron, as the weighted arms n2 willrelease the friction-flange n', thus preventing any more grain frombeing delivered to the band-cutter and the movable hopper-bottom andabsolutely preventing the choking of the machine, which would otherwiseoccur if the apron was not stopped.

When it is desired to transport the machine, the pins c2 c2 will beremoved and the carrier moved forward by balancing it upon the legs L L,and the rear end is then elevated by depressing the forward end untilthe rear end rests upon rollers P P, secured to the upper part of thecasing C, when the carrier will be pushed rearwardly and placed upon thetop of the thrasher.

A very advantageous result is accomplished by placing the governorbetween the drivingshaft of the carrier and the driving means therefor.By this construction, as soon as the speed of .the cylinder is loweredthe carrier is instantly stopped, so as not to feed any more grain intothe machine, while the bandcutters and the reciprocating hopper bottomcontinue to move and thus dispose of what grain is in the casing C,leaving it clear to receive grain as soon as the high speed is resumed,when the carrier is instantly thrown into gear automatically by thegovernor. j

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a band-cutter and feeder the combination with the reciprocatinghopper-bottom, of the removable bottom board for supporting one end ofthe same, said board having one edge supported adjacent to the concaveand provided with lateral projections adjacent to its other edge and thespring-hangers having recesses for engaging said projections,substantially as described.

2. In a band-cutter and feeder the combination with the band-cuttingdevices, of a reciprocating hopper-bottom, composed of slats and sawssecured to said slats, each saw having a flange engaging the lower faceof the next adjacent slat, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
